[BUG]OGLWin32(Object)>>error:

Chuck Hipschman
I'm pretty new to squeak, please let me know if I should be looking
for help elsewhere, (and where that would be :) TIA

I'm trying to follow a OpenGL tutorial posted on YouTube by user
sparaig.  It's only 9 lines of code

(Installer repository: 'http://source.squeak.org/FFI')
        install: 'FFI-Pools';
        install: 'FFI-Kernel';
        install: 'FFI-Tests'.
       
(Installer repository: 'http://www.squeaksource.com/CroquetGL')
        install: '3DTransform';
        install: 'OpenGL-Pools';
        install: 'OpenGL-Core'.
       
OpenGL example  "this is where the trouble begins"

The transcript shows:

Re: [BUG]OGLWin32(Object)>>error:

Nicolas Cellier
Most probably, some library was not found (I see the handle is 0).
If I open a browser on OGLWin32
    OGLWin32 browse.
In class definition, you see that handle is an instance variable.
Then looks at instance variable assignment (menu assignment... or
CTRL+a in class pane)
I get these two methods

OpenGL>>destroy
OpenGL>>initializeIn: bounds
        handle := self primCreateRenderer: 1 "B3DSoftwareRenderer" + 2
"B3DHardwareRenderer" + 4 "B3DStencilBuffer"
                x: bounds left y: bounds top w: bounds width h: bounds height.
        bufRect := bounds.
        handle ifNotNil:[glExt := OGLExtManager new ogl: self].
        ^handle ifNotNil:[self]

If I browse implementors of primCreateRenderer:x:y:w:h:, I get
OpenGL>>primCreateRenderer: flags x: x y: y w: w h: h
        <primitive: 'primitiveCreateRendererFlags' module:'B3DAcceleratorPlugin'>
        ^nil

It could be that your VM does not have the optional module
B3DAcceleratorPlugin...

I see you are using Squeak 4.1, and don't remember if it was already
available...
But you could search for top menu bar item  help->about this system.
If you have it, in the resulting window, select VM Modules and report
if B3DAcceleratorPlugin was loaded.
Also select VM General and report your results.

If you don't have this tool, then try

    SmalltalkImage current listBuiltinModules , SmalltalkImage current
listLoadedModules.

and

    SmalltalkImage current vmVersion.
